30% of 30000 =9000

We assume that the number 30000 is 100% because it's the output value of the task. 
We assume that x is the value we are looking for
If 30000 is 100% so we can write it down as 30000=100%
We know that x is 30% of the output value so we can write it down as x=30%. 
Now we have two simple equations
1) 30000=100%
2) x=30%
where left sides of both of them have the same units and both right sides have the same units so we can do something like that
30000/x=100%/30% Now we just have to solve the simple equation and we will get the solution we are looking for
Solution for what is 30% of 30000

30000/x=100/30
(30000/x)*x=(100/30)*x       we multiply both sides of the equation by x
30000=3.33333333333*x        we divide both sides of the equation by (3.33333333333) to get x
30000/3.33333333333=x 
9000=x 
x=9000

now we have: 
30% of 30000=9000

What number should be added to both sides in order to solve x^2 -8x=0
GREYUIT [131]

Answer:

16

Step-by-step explanation:

x^2 -8x=0

rewrite in this form and add 16 to both sides:

x² + 2(- 4)x + 16 = 0 + 16

(x - 4)² = 16 ( take square root of both sides )

x - 4 = ±  4

x =  4 ± 4

x=8 , x= 0

Identify the equations as parallel lines, perpendicular lines, or neither.
Alex

Answer:

B. Parallel

Step-by-step explanation:

Equation 1 simplified:   y = 3x+7

Equation 2 simplified: y = -x/3-3

The slopes are completely different, ruling out the possibility of the lines being parallel.

But we also see the slopes of the equations are opposite and negative to each other. Making the lines perpendicular.
